Timing diagram
Response to input fluctuations
Here is the timing diagram for the power supply:
T1 – ride through time – 0.5 to 1 cycles [ 10 – 20ms] VOUT remains within regulation – load dependent
T2 – hold up time - 15ms – VOUT stays above 30VDC
T3 – delay time – 10s – from when the AC returns within regulation to when the output starts rising in I2C mode
T4 – rise time - 120ms – the time it takes for VOUT to rise from 10% to 90% of regulation in I2C mode
T5 – power good warning – 3ms – the time between assertion of the PG signal and the output decaying below 30VDC.
T6 – hold up time of the 5VAUX output @ full load – 1s – from the time AC input failed
T7 – rise time of the 5VAUX output - 3.65ms – 5VAUX is available at least 450ms before the main output is within regulation

Unit in Power Limit or in Current Limit:
Control and Status
The power supply provides three means for monitor/control:
analog, PMBus™, or the GE Galaxy-based RS485 protocol.
Details of analog control and the PMBus™ based protocol are
provided in this data sheet. GE will provide separate
application notes on the Galaxy RS485 based protocol for
users to interface to the power supply. Contact your local GE
representative for details.
Control hierarchy: Some features, such as output voltage, can
be controlled both through hardware and firmware. For
example, the output voltage is controlled both by a signal pin
(Vprog) and firmware (Vout_command; 0x21).
Using output voltage as an example, the Vprog signal pin
voltage level sets the output voltage if its value is between
0.1Vdc and 3VDC. (see the Vprog section). When the
programming signal Vprog is a no connect, the output voltage
is set at the default value of 23VDC. When the programming
signal is between 0V and 0.1V, the output will be 23Vdc.
The signal pin controls the feature it is configuring until a
firmware command is executed. However, once the firmware
command has been executed, the signal pin is ignored. In the
above example, the power supply will no longer ‘listen’ to the
Vprog pin if the Vout_command has been executed.
In summary, signals such as Vprog are utilized for setting the
initial default value and for varying the value until firmware
based control takes over. Once firmware control is executed,
hardware based control is relinquished so the processor can
clearly decide who has control.
Analog controls: Details of analog controls are provided in
this data sheet under Feature Specifications.
Signal Reference: Unless otherwise noted, all signals are
referenced to Logic_GRD. See the Signal Definitions Table at
the end of this document for further description of all the
signals.
Logic_GRD is isolated from the main output of the power
supply for PMBus communications. Communications and the
5V standby output are not connected to main power return
(Vout(-)) and can be tied to the system digital ground point
selected by the user. (Note that RS485 communications is
referenced to Logic_Gnd because the output voltage can
exceed the SELV limit).
Logic_GRD is capacitively coupled to Frame_GRD inside the
power supply. The maximum voltage differential between
Logic_GRD and Frame_GRD should be less than 100VDC.
Delayed overcurrent shutdown during startup: This power
supply is programmed to stay in a constant current state for
up to 20 seconds during power up. This delay has been
introduced to permit the orderly application of input power to
a subset of paralleled front-ends during power up. If the
overload persists beyond the 20 second delay, the front-end
will revert to its programmed state of overload protection.
August 30, 2021
When output voltage
is > 30VDC the Output LED will continue blinking.
When output voltage is < 23VDC, if the unit is in the RESTART
mode, it goes into hiccup. When the unit is ON the output LED
is ON, when the unit is OFF the output LED is OFF.
When the unit is in latched shutdown the output LED is OFF.
The power supply will delay overcurrent shutdown for 3
seconds to allow the user equipment to shed load. Voltages
below 5Vdc are considered a deep overload/short circuit that
will cause an immediate shutdown.
Auto restart: Auto-restart is the default configuration for
over-current and over-temperature shutdowns. These
features are configured by the PMBus™ fault_response
commands
An overvoltage shutdown is followed by three attempted
restarts, each restart delayed 1 second, within a 1 minute
window. If within the 1 minute window three attempted
restarts failed, the unit will latch OFF. If within the 1 minute
less than 3 shutdowns occurred then the count for latch OFF
resets and the 1 minute window starts all over again.
Restart after a latchoff: PMBus™ fault_response commands
can be configured to direct the power supply to remain
latched off for over_temperature and over_current.
To restart after a latch off either of five restart mechanisms
are available.
1. The hardware pin ON/OFF may be cycled OFF and
then ON.
2. The unit may be commanded to restart via i2c
through the Operation command by cycling the
output OFF followed by ON.
3. Remove and reinsert the unit.
4. Turn OFF and then turn ON AC power to the unit.
5. Changing firmware from latch off to restart.
Each of these commands must keep the power supply in the
OFF state for at least 2 seconds, with the exception of
changing to restart.
A successful restart shall clear all alarm registers, set the
restarted successful bit of the Status_2 register.
A power system that is comprised of a number of power
supplies could have difficulty restarting after a shutdown
event because of the non-synchronized behavior of the
individual power supplies. Implementing the latch-off
mechanism permits a synchronized restart that guarantees
the simultaneous restart of the entire system.
A synchronous restart can be implemented by;
Issuing a GLOBAL OFF and then ON command to all power
supplies,
or Toggling Off and then ON the ON/OFF (ENABLE) signal
or Removing and reapplying input power to the entire
system.
The power supplies should be turned OFF for at least 20 – 30
seconds in order to discharge all internal bias supplies and
reset the soft start circuitry of the individual power supplies.

Control Signals
Protocol: This signal pin defines the communications mode
setting of the power supply. Two different states can be
configured. State #1 is the I2C application in which case the
protocol pin should be left a no-connect. State #2 is the
RS485 mode application in which case a resistor value
between 1kΩ and 5kΩ should be present between this pin and
Vout ( - ).
Device address in I2C mode: Address bits A3, A2, A1, A0 set
the specific address of the µP in the power supply. With these
four bits, up to sixteen (16) power supplies can be
independently addressed on a single I²C bus. These four bits
are configured by two signal pins, Unit_ID and Rack_ID. The
least significant bit x (LSB) of the address byte is set to either
write [0] or read [1]. A write command instructs the power
supply. A read command accesses information from the
power supply.

Global Broadcast: Instruct all power supplies to respond
simultaneously. The GLOBAL BROADCAST command should
only be executed as a write instruction. The power supply
should issue an ‘invalid command’ if a global ‘read’ is
attempted.
An output voltage change instruction should be executed in ≤
60ms for a V of ≤ 10V.
A ‘system’ output voltage change for paralleled power
supplies requires global broadcast. This command is also used
to control the main output of a system. Unfortunately, this
command is vulnerable to error. The ACK bit does not assure
that all power supplies responded. To be certain that each
power supply responded to the global instruction, a READ
August 30, 2021
Voltage programming (Vprog): Hardware voltage
programming controls the output voltage until a software
command to change the output voltage is executed. Once a
software voltage programming command is executed, the
software voltage instruction permanently overrides the
hardware margin setting. The power supply no longer listens
to the hardware margin setting until power to the controller is
interrupted, for example if input power or bias power is
recycled.
The Vprog pin voltage level, which is referenced to Logic_GRD,
is configured by the user as shown in the graph above. It must
be set in order for the power supply to know what its setting
should be.
Programming of the Vprog signal level can be accomplished
either by a resistor divider or by a voltage source injecting a
precision voltage level into the Vprog pin. Above 3Vdc the
power supply sets the output to default output. Factory set
default output is 23V. Below 0.1Vdc, the power supply sets its
output voltage to 23Vdc. See the accompanying
implementation of hot plug for further information on hotplug performance.
When bias power powering the controller is recycled, the
controller restarts into its default configuration, programmed
to set the output as instructed by the Vprog pin. Again,
subsequent software commanded instructions permanently
override the margin setting.
If the output voltage of the power supply is software
controlled, the Vprog voltage level should be set to a safety
level that power supplies inserted into a live bus (hot plug)
should be powered into, until subsequent software
instructions tell the power supplies on the bus the desired
output voltage setting. One such voltage level setting is
23Vdc. The hot plugged power supply will produce 23Vdc
until it is commanded by the controller to another setting.

Load share (Ishare): This is a single wire analog signal that is
generated and acted upon automatically by power supplies
connected in parallel. Ishare pins should be connected to each
other. No resistors or capacitors should get connected to this
pin.
ON/OFF: Controls the main 65VDC output when either analog
control or PMBus protocols are selected, as configured by the
Protocol pin. This pin must be pulled low to turn ON the
power supply. The power supply will turn OFF if either the
ON/OFF or the Interlock pin is released. This signal is
referenced to Logic_GRD. Note that in RS485 mode this pin is
ignored.
Interlock: This is a shorter pin utilized for hot-plug
applications to ensure that the power supply turns OFF before
the power pins are disengaged. It also ensures that the power
supply turns ON only after the power pins have been engaged.
Must be connected to V_OUT ( - ) for the power supply to be
ON.
Module Present: This signal is tied to Logic_GRD inside the
power supply. The intent is to provide a signal to the system
that a power supply is present in the slot.
8V_INT: Single wire connection between power supplies. It
provides bias to the DSP of an unpowered power supply.
Pull-up resistors: The clock, data, and Alert# lines do not have
any internal pull-up resistors inside the power supply. The
customer is responsible for ensuring that the transmission
impedance of the communications lines complies with I2C and
SMBus standards.
Serial Clock (SCL): The clock pulses on this line are generated
by the host that initiates communications across the I²C Serial
bus. This signal needs to be pulled HI externally through a
resistor as necessary to ensure that rise and fall time timing
and the maximum sink current is in compliance to the I²C
/SMBus specifications.
Serial Data (SDA): This line is a bi-directional data line. This
signal needs to be pulled HI externally through a resistor as
necessary to ensure that rise and fall time timing and the
maximum sink current is in compliance to the I²C /SMBus
specifications.
Digital Feature Descriptions
PMBus™ compliance: The power supply is fully compliant to
the Power Management Bus (PMBus™) rev1.2 requirements.
This Specification can be obtained from www.pmbus.org.
‘Manufacturer Specific’ commands are used to support
additional instructions that are not in the PMBus™
specification.
Status Signals
Power Good Warning (PG#): This signal is HI when the main
output is being delivered and goes LO if the main output is
about to decay below regulation. Note that should a
catastrophic failure occur, the signal may not be fast enough
to provide a meaningful warning. PG# also pulses at a 1ms
duty cycle if the unit is in overload.
Fault#: A TTL compatible status signal representing whether a
Fault occurred. This signal needs to be pulled HI externally
through a resistor. This signal goes LO for any failure that
requires power supply replacement. These faults may be due
to:
•
•
•
•
All signals are referenced to ‘Logic_GRD’.
Fan failure
Over-temperature shutdown
All communication over the PMBus interface must support the
Packet Error Checking (PEC) scheme. The PMBus master must
generate the correct PEC byte for all transactions, and check
the PEC byte returned by the power supply.
The Alert# response protocol (ARA) whereby the PMBus
Master can inquire who activated the Alert# signal is also
supported. This feature is described in more detail later on.
Non-volatile memory is used to store configuration settings.
Not all settings programmed into the device are automatically
saved into this non-volatile memory. Only those specifically
identified as capable of being stored can be saved. (see the
Table of Commands for which command parameters can be
saved to non-volatile storage).
Over-voltage shutdown
Internal Fault
Non-supported commands: Non-supported commands are
flagged by setting the appropriate STATUS bit and issuing an
Alert# to the ‘host’ controller.
Over temp warning (OTW#): Omitted.
If a non-supported read is requested the power supply will
return 0x00h for data.
Serial Bus Communications
The I²C interface facilitates the monitoring and control of
various operating parameters within the unit and transmits
these on demand over an industry standard I²C Serial bus.
August 30, 2021
Data out-of-range: The power supply validates data settings
and sets the data out-of-range bit and Alert# if the data is not
within acceptable range.

Master/Slave: The ‘host controller’ is always the MASTER.
Power Supplies are always SLAVES. SLAVES cannot initiate
communications or toggle the Clock. SLAVES also must
respond expeditiously at the command of the MASTER as
required by the clock pulses generated by the MASTER.
Clock stretching: The ‘slave’ µController inside the power
supply may initiate clock stretching if it is busy and it desires
to delay the initiation of any further communications. During
the clock stretch the ‘slave’ may keep the clock LO until it is
ready to receive further instructions from the host controller.
The maximum clock stretch interval is 25ms.
The host controller needs to recognize this clock stretching,
and refrain from issuing the next clock signal, until the clock
line is released, or it needs to delay the next clock pulse
beyond the clock stretch interval of the power supply. Note
that clock stretching can only be performed after completion
of transmission of the 9th ACK bit, the exception being the
START command.
Clock
Stretch
Figure 15. Example waveforms showing clock stretching.
I²C Bus Lock-Up detection: The device will abort any
transaction and drop off the bus if it detects the bus being
held low for more than 35ms.
Communications speed: Both 100kHz and 400kHz clock rates
are supported. The power supplies default to the 100kHz clock
rate.
Packet Error Checking (PEC): The power supply will not
respond to commands without the trailing PEC. The integrity
of communications is compromised if packet error correction
is not employed. There are many functional features,
including turning OFF the main output, that require validation
to ensure that the desired command is executed.
PEC is a CRC-8 error-checking byte, based on the polynomial
C(x) = x8 + x2 + x + 1, in compliance with PMBus™
requirements. The calculation is based in all message bytes,
including the originating write address and command bytes
preceding read instructions. The PEC is appended to the
message by the device that supplied the last byte.
Alert#: The power supply can issue Alert# driven from either
its internal micro controller (µC) or from the I2C bus master.
Normally this signal is HI. The signal will change to its LO level
if the power supply has changed states and the signal will be
latched LO until the power supply receives a ‘clear_faults’
instruction.
The signal will be triggered for any state change, including the
following conditions;
•
•
•
•
•
•
•
•
•
•
VIN under or over voltage
Vout under or over voltage
IOUT over current
Over Temperature warning or fault
Fan Failure
Communication error
PEC error
Invalid command
Internal faults
Alert# is asserted during power up to notify the master
that a new power supply has been added to the bus.
The power supply will clear the Alert# signal (release the
signal to its HI state) upon the following events:
•
Receiving a CLEAR_FAULTS command
•
Bias power to the processor is recycled
The power supply will re-assert the Alert line if the internal
state of the power supply has changed, even if that
information cannot be reported by the status registers until a
clear_faults is issued by the host. If the Alert asserts, the host
should respond by issuing a clear_faults to retire the alert line
(this action also provides the ability to change the status
registers). This action triggers another Alert assertion because
the status registers changed states to report the latest state of
the power supply. The host is now able to read the latest
reported status register information and issue a clear_faults to
retire the Alert signal.
Re-initialization: The I2C code is programmed to re-initialize if
no activity is detected on the bus for 5 seconds. Reinitialization is designed to guarantee that the I2C µController
does not hang up the bus. Although this rate is longer than the
timing requirements specified in the SMBus specification, it
had to be extended in order to ensure that a re-initialization
would not occur under normal transmission rates. During the
few µseconds required to accomplish re-initialization the I2C
µController may not recognize a command sent to it. (i.e. a
start condition).
Read back delay: The power supply issues the Alert#
notification as soon as the first state change occurred. During
an event, a number of different states can be transitioned to
before the final event occurs. If a read back is implemented
rapidly by the host a successive Alert# could be triggered by
the transitioning state of the power supply. In order to avoid
successive Alert# s and read back and also to avoid reading a
transitioning state, it is prudent to wait more than 2 seconds
after the receipt of an Alert# before executing a read back.
This delay will ensure that only the final state of the power
supply is captured.
The µC driven Alert# signal informs the ‘master/host’
controller that either a STATE or ALARM change has occurred.

Status and Alarm registers: The registers are updated with
the latest operational state of the power supply. For example,
whether the output is ON or OFF is continuously updated with
the latest state of the power supply. However, alarm
information is maintained until a clear_faults command is
received from the host. For example, the shutdown or
OC_fault bits stay in their alarmed state until the host clears
the registers.
A clear_faults clears all registers. If a fault persists after the
clear_faults is commanded, the register bit annunciating the
fault is reset again.

Clear_faults (0x03): Clears all STATUS and FAULT registers
and resets the Alert# line. This command is always executable.
If a fault persists after the issuance of the clear_faults
command, the specific registers indicating the fault first clears
but then get set again to indicate that the unit is still in the
fault state.
WRITE_PROTECT register (0x10): Used to control writing to
the PMBus device. The intent of this command is to provide
protection against accidental changes. All supported
commands may have their parameters read, regardless of the
write_protect settings. The contents of this register cannot be
stored into non-volatile memory using the Store_user_code
command. The default setting of this register is
enable_all_writes, write_protect 0x00h. The write_protect
command must always be accepted.

Restore_Default_All (0x12): Restores all operating register
values and responses to the factory default parameters set in
the power supply. The factory default cannot be changed.
Restore_default_code (0x14): Restore only a specific register
parameter into the operating register section of the power
supply.
Store_user_code (0x17): Changes the user default setting of a
single register. In this way, some protection is offered to
ensure that only those registers that are desired to be
changed are in fact changed.
Restore_user_code (0x18): Restores the user default setting
of a single register.
Vout_mode (0x20): This is a ‘read only’ register. The upper
three bits specify the supported data format, in this case
Linear mode. The lower five bits specify the exponent of the
data in two’s complement binary format for output voltage
related commands, such as Vout_command. These commands
have a 16 bit mantissa. The exponent is fixed by the power
supply and is returned by this command

Vout_Command (0x21) : Used to dynamically change the
output voltage of the power supply. This command can also
be used to change the factory programmed default set point
of the power by executing a store-user instruction that
changes the user default firmware set point.

•
•Input: 100-240 Vac; 3500W capable; 65 Vdc @ 3500W; 5 Vdc @ 10W
•
The default set point can be overridden by the Vprog signal
pin which is designed to override the firmware based default
setting during turn ON.
In parallel operation, changing the output voltage should be
performed simultaneously to all power supplies using the
Global Address (Broadcast) feature. If only a single power
supply is instructed to change its output, it may attempt to
source all the required power which can cause either a power
limit or shutdown condition.
Software programming of output voltage permanently
overrides the set point voltage configured by the Vprog signal
pin. The power supply no longer looks at the ‘Vprog pin’ and
will not respond to any hardware voltage settings. If power is
removed from the µController it will reset itself into its default
configuration looking at the Vprog signal for output voltage
control. In many applications, the Vprog pin is used for
setting initial conditions, if different that the factory setting.
Software programming then takes over once I2C
communications are established.
To properly hot-plug a power supply into a live backplane, the
system generated voltage should get re-configured into either
the factory adjusted firmware level or the voltage level
reconfigured by the Vprog pin. Otherwise, the voltage state of
the plugged-in power supply could be significantly different
than the powered system.
Programmed voltage range: 23VDC – 65VDC.
Fan_command_1 (0x3B): This command instructs the power
supply to increase the speed of both fans above what is
internally required. The transmitted data byte represents the
hex equivalent of duty cycle in percentage, i.e. 100% = 0 x 64h.
The command can increase or decrease fan speed. An
incorrect value will result in a ‘data error’.
Sending 00h tells the power supply to revert to its internal
control.
Vout_OV_fault_limit (0x40): Sets the value at which the main
output voltage will shut down. This level can be permanently
changed and stored in non-volatile memory.
Vout_OV_fault_response (0x41): This is a ‘read only’ register.
The only allowable state is a latched state after three retry
attempts.
An overvoltage shutdown is followed by three attempted
restarts, each successive restart delayed 1 second. If within a
1 minute window, three attempted restarts failed, the unit
will latch OFF. If less than 3 shutdowns occur within the 1
minute window then the count for latch OFF resets and the 1
minute window starts all over again. This performance cannot
be changed.
Restart after a latched state: Either of four restart
mechanisms is available;
•
A voltage programming example: The task: set the output
voltage to 65.0VDC
•
This power supply supports the linear mode of conversion
specified in the PMBus™ specification. The supported output
voltage exponent is documented in the Vout_mode (0x20)
command. The exponent for output voltage setting is 2-9 (see
the PMBus™ specification for reading this command).
Calculate the required voltage setting to be sent; 65 x 29 =
33280. Convert this decimal number into its hex equivalent:
8200 and send it across the bus LSB first and then MSB; E664
with the trailing PEC.
•
Vin_ON (0x35): This is a ‘read only’ register that informs the
controller at what input voltage level the power supply turns
ON. The default value is tabulated in the data section. The
value is contingent on whether the power supply is operating
in the low_line or high_line mode.
Vin_OFF (0x36): This is a ‘read only’ register that informs the
controller at what input voltage level the power supply turns
OFF. The default value is tabulated in the data section. The
value is contingent on whether the power supply is operating
in the low_line or high_line mode.
Fan_config_1_2 (0x3A): This command requires that the fan
speed be commanded by duty cycle. Both fans must be
commanded simultaneously. The tachometer pulses per
revolution is not used. Default is duty cycle control.
August 30, 2021
•
The hardware pin ON/OFF may be cycled OFF and then
ON.
The unit may be commanded to restart via i2c through
the Operation command by first turning OFF then turning
ON.
The third way to restart is to remove and reinsert the
unit.
The fourth way is to turn OFF and then turn ON AC power
to the unit.
A successful restart clears all STATUS and ALARM registers.
A power system that is comprised of a number of power
supplies could have difficulty restarting after a shutdown
event because of the non-synchronized behavior of the
individual power supplies. Implementing the latch-off
mechanism permits a synchronized restart that guarantees
the simultaneous restart of the entire system.
A synchronous restart can be implemented by;
•
•
•
Issuing a GLOBAL OFF and then a GLOBAL ON command
to all power supplies
Toggling Off and then ON the ON/OFF signal, if this signal
is paralleled among the power supplies.
Removing and reapplying input power to the entire
system.
The power supplies should be OFF for at least 20 – 30 seconds
in order to discharge all internal bias supplies and reset the
soft start circuitry of the individual units.
Vout_OV_warn_limit (0x42): Sets the value at which a
warning will be issued that the output voltage is too high.
Exceeding the warning value will set the Alert# signal.

Vout_UV_warn_limit (0x43): Sets the value at which a
warning will be issued that the output voltage is too low.
Reduction below the warning value will set the Alert# signal.
Vout_UV_fault_limit (0x44): Sets the value at which the
power supply will shut down if the output gets below this
level. This register is masked if the UV is caused by
interruption of the input voltage to the power supply.
Vout_UV_fault_response (0x45): Sets the response if the
output voltage falls below the UV_fault_limit. The default
UV_fault_response is restart (0xC0). The only two allowable
states are latched (0x80) and restart (0xC0).
Iout_OC_fault_limit (0x46): Sets the value at which the power
supply will shut down. The default OC_fault_limit is 60A.This
level can be permanently changed and stored in non-volatile
memory. And this parameter is only effective in high line. It is
useless in lowline condition.
The Low Line level is not adjustable, it is set at 30A.
Iout_OC_fault_response (0x47): Sets the response if the
output overload exceeds the OC_Fault_limit value. The default
OC_fault_response is hiccup (0xF8). The only two allowable
states are latched (0xC0) or hiccup. The response is the same
for both low_line and high_line operations.
Iout_OC_warn_limit (0x4A): Sets the value at which the
power supply issues a warning that the output current is
getting too close to the shutdown level at high line.
OT_fault_limit (0x4F): Sets the value at which the power
supply responds to an OT event, sensed by the “dc-secondary”
sensor. The response is defined by the OT_fault_response
register.
OT_fault_response (0x50): Sets the response if the output
overtemperature exceeds the OT_Fault_limit value. The
default OT_fault_response is hiccup (0xC0). The only two
allowable states are latched (0x80) or hiccup.
OT_warn_limit (0x51): Sets the value at which the power
supply issues a warning when the “dc-secondary”
temperature sensor exceeds the warn limit.
Vin_OV_fault_limit (0x55): Sets the value at which the power
supply shuts down because the input voltage exceeds the
allowable operational limit. The default Vin_OV_fault_limit is
set at 300Vac.
Vin_OV_fault_response (0x56): Sets the response if the input
voltage level exceeds the Vin_OV_fault_limit value. The
default Vin_OV_fault_response is restart (0xC0). The only two
allowable states are latched (0x80) and restart (0xC0).

Manufacturer-Specific PMBusTM Commands
Many of the manufacturer-specific commands read back more
than two bytes. If more than two bytes of data are returned,
the standard SMBusTM Block read is utilized. In this process,
the Master issues a Write command followed by the data
transfer from the power supply. The first byte of the Block
Read data field sends back in hex format the number of data
bytes, exclusive of the PEC number, that follows. Analog data
is always transmitted LSB followed by MSB. A No-ack following
the PEC byte signifies that the transmission is complete and is
being terminated by the ‘host’.
Mfr_Specific Status and alarm registers: The content and
partitioning of these registers is significantly different than the
standard register set in the PMBus™ specification. More
information is provided by these registers and they are either
accessed rapidly, at once, using the ‘multi parameter’ read
back scheme of this document, or in batches of two STATUS
and two ALARM registers.

LEDs test ON: Will turn-ON simultaneously the front panel
LEDs of the power supply sequentially 7 seconds ON and 2
seconds OFF until instructed to turn OFF. The intent of this
function is to provide visual identification of the power supply
being talked to and to visually verify that the LEDs operate and
driven properly by the micro controller.
LEDs test OFF: Will end the LED test, and cause them to
revert to normal status indications.
Service LED ON: Requests the power supply to flash-ON the
Service (ok-to-remove) LED. The flash sequence is
approximately 0.5 seconds ON and 0.5 seconds OFF.
Service LED OFF: Requests the power supply to turn OFF the
Service (ok-to-remove) LED.
OR’ing Test: This command verifies functioning of output
OR’ing. At least two paralleled power supplies are required.
The host should verify that N+1 redundancy is established. If
N+1 redundancy is not established the test can fail. Only one
power supply should be tested at a time.
Verifying test completion should be delayed for approximately
30 seconds to allow the power supply sufficient time to
properly execute the test.
Failure of the isolation test is not considered a power supply
FAULT because the N+1 redundancy requirement cannot be
verified. The user must determine whether a true isolation
fault indeed exists.
supply will revert to its programmed state of overload
protection.
Unit in Power Limit or in Current Limit: When output voltage
is > 30VDC the Output LED will continue blinking.
When output voltage is < 30VDC, if the unit is in the RESTART
mode, it goes into hiccup after a 3 second delay. When the DC
power is ON the output LED is ON, when the DC power is OFF
the output LED is OFF.
When the unit is in latched shutdown the output LED is OFF.
Restart after a latchoff: PMBus™ fault_response commands
can be configured to direct the power supply to remain
latched off for over_voltage, over_temperature and
over_current.
To restart after a latch off either of five restart mechanisms
are available.
1. The hardware pin ON/OFF may be cycled OFF and
then ON.
2. The unit may be commanded to restart via i2c
through the Operation command by cycling the
output OFF followed by ON.
3. Remove and reinsert the unit.
4. Turn OFF and then turn ON AC power to the unit.
5. Changing firmware from latch off to restart.
Each of these commands must keep the power supply in the
OFF state for at least 2 seconds, with the exception of
changing to restart.
Single Master Control:
A successful restart shall clear all alarm registers, set the
restarted successful bit of the Status_2 register.
One I2C clock, data, and Alert# signal provides
communications.
A power system that is comprised of a number of power
supplies could have difficulty restarting after a shutdown
event because of the non-synchronized behavior of the
individual power supplies. Implementing the latch-off
mechanism permits a synchronized restart that guarantees
the simultaneous restart of the entire system.
A synchronous restart can be implemented by;
1. Issuing a GLOBAL OFF and then ON command to all power
supplies,
2. Toggling Off and then ON the ON/OFF (ENABLE) signal
3. Removing and reapplying input power to the entire
system.
General performance descriptions
Default state: Power supplies are programmed in the default
state to automatically restart after a shutdown has occurred.
The default state can be reconfigured by changing non-volatile
memory (Store_user_code).
Delayed overcurrent shutdown during startup: Power
supplies are programmed to stay in a constant current state
for up to 20 seconds during power up. This delay has been
introduced to permit the orderly application of input power to
a subset of paralleled power supplies during power up. If the
overload persists beyond the 20 second delay, the power
August 30, 2021
The power supplies should be turned OFF for at least 20 – 30
seconds in order to discharge all internal bias supplies and
reset the soft start circuitry of the individual power supplies.
Auto_restart: Auto-restart is the default configuration for
over-current and over-temperature shutdowns. These
features are configured by the PMBus™ fault_response
commands.
An overvoltage shutdown is followed by three attempted
restarts, each restart delayed 1 second, within a 1 minute
window. If within the 1 minute window three attempted
restarts failed, the unit will latch OFF. If within the 1 minute

address. The system can detect the hot-plug activity by
polling the unit_present signal pin.
Fault Management
The one exception for this instruction delay recommendation
is execution of a ‘global or broadcast’ instruction to all power
supplies simultaneously, which does not utilize the power
supply’s own address.
The power supply recognizes that certain transitionary states
can occur before a final state is reached. The STATUS and
ALARM registers will not be frozen into a notification state
until the final state is reached. Once a final state is reached
the Alert# signal is set and the STATUS and ALARM registers
will not get reinstated until a clear_faults is issued by the
master. The only exception is that additional state changes
may be added to the original list if further changes are noted.
The power supply differentiates between internal faults that
are within the power supply and external faults that the
power supply protects itself from, such as overload or input
voltage out of limits. The FAULT LED, FAULT PIN or i2c alarm is
not asserted for EXTERNAL FAULTS. Every attempt is made to
annunciate External Faults. Some of these annunciations can
be observed by looking at the input LEDs. These fault
categorizations are predictive in nature and therefore there is
a likelihood that a categorization may not have been made
correctly.
Input voltage out of range: The Input LED will continue
blinking as long as sufficient power is available to power the
LED. If the input voltage is completely gone the Input LED is
OFF.
The recommended procedure for hot removal in controller
based systems is the following: The system controller should
signal the craft person which power supply is to be removed.
This is suggested so that the correct power supply is removed
by the craft person. The controller turns the service LED ON,
thus informing the craft person that the identified power
supply can be removed from the system. The system
controller should then poll the rectifier_present signal to
verify when the power supply has been inserted. Once the
insertion is detected, the system controller should time out
for 1 second before sending out a non-‘global or broadcast’
address based instruction. . At the end of the time out all
communications can resume.
The hot-plugged power supply will turn ON to the voltage
level set by the Vprog pin. As described in the section on
setting the Vprog pin, the system needs to set the output
voltage to a level that would not cause harm or malfunction.
For this power supply, the recommended output voltage
setting would be 23Vdc. The power supply would stay at this
level until a firmware instruction tells it to change its setting.
For systems controlled via the Vprog pin (output controlled by
hardware instead of firmware) no special settings or
configurations are required.
Failure Prediction
State Change Definition
A state_change is an indication that an event has occurred
that the MASTER should be aware of. The following events
shall trigger a state_change;
•
•
Initial power-up of the system when AC gets turned ON.
This is the indication from the power supply that it has
been turned ON. Note that the master needs to read the
status of each power supply to reset the
system_interrupt.
Any changes in the bit pattern of either the PMBus
standard STATUS or the mfr_specific STATUS registers
should trigger the Alert# signal.
Hot plug procedures
Careful system control is recommended when hot plugging a
power supply into a live system. It takes about 1 second for a
power supply to configure its address on the bus based on the
analog voltage levels present on the backplane. If
communications are not stopped during this interval, multiple
power supplies may respond to specific instructions because
the address of the newly inserted power supply always
defaults to xxxx000 until the power supply has configured its
August 30, 2021
Alarm warnings that do not cause a shutdown are indicators
of potential future failures of the power supply. For example,
if a thermal sensor failed, a warning is issued but an
immediate shutdown of the power supply is not warranted.
Another example of potential predictive failure mechanisms
can be derived from information such as fan speed when
multiple fans are used in the same power supply. If the speed
of the fans varies by more than 20% from each other, this is an
indication of an impending fan wear out.
The goal is to identify problems early before a protective
shutdown would occur that would take the power supply out
of service.

and the compatibility code of the upgraded
Remote upgrade
program for each of the three processors
This section describes, at a high-level, the recommended reprogramming process for the three internal micro controllers
inside the power supply when the re-programming is
implemented in live, running, systems.
The process has been implemented in visual basic by GE
Critical Power for controller based systems. GE Critical Power
will share its development with customers who are interested
to deploy the re-programming capability into their own
controllers.
For some customers, internal system re-programming is either
not feasible or not desired. These customers may obtain a reprogramming kit from GE Critical Power. This kit contains a
turn-key package with the re-program firmware.
Concept Description: The power supply contains three
independent µControllers. The boost (PFC) section is
controlled by the primary µController. The secondary DC-DC
converter is controlled by the secondary µController, and I2C
communications are being handled by the I2C Interface
µController.

Upgrade Status Indication: The FAULT LED is utilized for
indicating the status of the re-programming process.
Each of the µControllers contains a boot loader section and an
application section in memory. The purpose of the boot
loader section is to facilitate the upgrading capability
described here. All the commands for upgrading and memory
space required for incrementally changing the application
code are in this section. The application section contains the
running code of the power supply.
The system controller receives the upgrade package. It should
first check whether an upgrade is required followed by
upgrading those processors, one at a time, that are required
to be upgraded. Each processor upgrade needs to be validated
and once the upgrade is successfully completed the boot
loader within each processor will permit the application to run
after a reset. If the validation fails the boot loader will stay in
its section. The system controller can attempt another
upgrade session to see if it would complete successfully.

Upgrade procedure
1. Initialization: To execute the re-programming/upgrade in
the system, the power supply to be re-programmed must
first be taken OFF-line prior to executing the upgrade. If
the power supply is not taken OFF-line by the system
controller, the boot loader will turn OFF the output prior
to continuing with the re-programming operation.
Note: Make sure that sufficient power is provided by the
remaining on-line power supplies so that system
functionality is not jeopardized.

After completion of the first data packet upload the Boot
loader increments the sequence number. A subsequent read
to the boot loader will return the incremented sequence
number and a STATUS byte. This is a validity check to ensure
that the sequence number is properly kept. The returned
STATUS byte is the same as the application status response. It
is appended here automatically to save the execution of
another command. It should be checked to ensure that no
errors are flagged by the boot loader during the download. If
an error occurred, terminate the download load and attempt
to reprogram again.

Sequence number validation takes place after each data block
transfer. The next data block transfer starts with the sequence
number received from the boot loader.
Data:
1=enter boot block (software reboot)
2=erase
3=done
4=exit23 boot block (watchdog reboot)
The host keeps track of the upload and knows when the
upload is completed.
Note: The target µC field is ignored for enter and exit
commands. During this process if the output of the power
supply was not turned OFF the boot loader will turn OFF the
output
10. Erase and program each µC using the Boot Loader
command, starting with the PFC.
11. Wait at least 1 second after issuing an erase command
to allow the µC to complete its task.
12. Use command 0xE5 to verify that the PFC µC is erased.
The returned status byte should be 0x81.
13. Use the Data Transfer command to update the
application of the target µC.
14. Execute a Boot loader command to tell the PFC µC that
the transfer is done.
At the completion signal, the PFC µC should calculate the
PEC value of the entire application. The last two bytes of
the loaded application were the CRC-16 based PEC
calculation.
Wait for at least 1 second to allow time for the PFC µC to
calculate the error checking value.
15. Execute an Application status command to verify that the
error check is valid. The returned status should be 0x80.

The ‘exit boot block’ command is only successful if all applications
are valid, otherwise, control remains in the boot block

Accessing the event records
The event records are accessed by uploading the entire
contents of the black box of the power supply into a folder
assigned by the user. Within the I2C protocol this upload is
accomplished by the upload_black_box (0xF0) command
described below. GE provides a Graphical User Interface
(GUI) that de-codes the contents of the black box into a set of
records that can be reviewed by the user.
Upload black box(0xF0): This command executes the upload
from the power supply to a file of the user’s choice.
The 100ms delay prior to the restart is mandatory to provide
enough time for the power supply to gather the required data
from the secondary DSP controller.

This feature of the black box includes information on the
repetition and duration of certain events in order to
understand the long-term operational state of the power
supply. The events are placed into defined buckets for further
analysis. For example; the power supply records how long the
output current was provided in certain load ranges.

Error handling: The Boot loader will not start the application
if errors occurred during the re-program stage. The controlling
program could restart the upgrade process or terminate the

1. A rolling event Recorder
2. Operational Use Statistics
The rolling event recorder
The purpose of the black box is to provide operational
statistics as well as fault retention for diagnostics following
either recoverable or non-recoverable fault events. Sufficient
memory exists to store up to 5 time-stamped snapshot
records (pages) that include the state of the status and alarm
registers and numerous internal measurement points within
the power supply. Each record is stored into nonvolatile
memory at the time when a black box trigger event occurs.
Once five records are stored, additional records over-write the
oldest record.
The memory locations are cleared, when the product is
shipped from the GE factory.

Latched status states until cleared
The following bits are sticky until cleared by the customer
Or’ing test failed or passed: The customer needs to delete the information (clear_faults) thus indicating that he received the
information.
Shutdown: It tells the customer that the power supply output has been turned OFF
OV, UV, OC, fan, input, unknown warnings & faults, CML Errors, Internal or External Fault: must be sticky
OC and OT response registers are in their own confined state. The only way these should change is by commanding the change by the
controller. Therefore, they are sticky because a clear_faults should never change them.
All fault information is sticky (if the fault persists after a clear_faults has been issued then the fault state will reassert), all operational
state information is not sticky.
